The company claim that Theradome, which was the brainchild of former Nasa scientist Tamim Hamid, is unique as this advanced technology can be used at home.

They say the headset contains high efficiency lasers that produce virtually no heat but allow the maximum amount of light to be delivered.

For the first 18 to 24 weeks of use the headset is designed to reverse the shrinking of hair follicles to stop further hair loss.

After 28 weeks of regular wear, the helmet claims to stimulate hair re-growth by increasing blood flow to the scalp and hair follicles, stimulating microcirculation and improving the metabolism of cells.

Speaking to the MailOnline, Dr Bessam Farjo, Medical Director of the Institute of Trichologists, said: "I do believe that laser technology has validity, but I’m sceptical of the specific claims made by Theradome GB that this particular headgear has the ability to increase the hair shaft diameter by 200 per cent. I have not seen any scientific evidence to support this."

If you want to try out the helmet for yourself you'll have to be prepared to pay - the headgear costs $795 (£473 plus shipping).
